How Whatsapp Works?

Whatsapp is a messaging app that has become a daily essential for people worldwide. But have you ever wondered how it works?

Firstly, when you send a message on Whatsapp, it is encrypted end-to-end, which means that only the sender and receiver can read the message. It’s a security feature that has made Whatsapp a popular choice for confidential conversations.

Secondly, the app uses your phone’s internet connection to send messages, voice notes, and make calls, rather than using your phone’s SMS or MMS service. This means that it is much cheaper to use than traditional messaging services, and it is more convenient too.

Finally, Whatsapp has some unique features that set it apart from other messaging apps, such as the ability to create groups, broadcast messages, and share files of various types and sizes. All these features are possible thanks to the programming language that Whatsapp is built on.

In the next sections, we will explore more about the programming language behind Whatsapp and why it is essential to understand it.

Introduction to Whatsapp Architecture

Whatsapp is a popular messaging application used by millions of people worldwide. The architecture of Whatsapp is designed to provide a fast and secure messaging service. The app has two main components: the client application and the server-side infrastructure. The client application runs on the user’s device, while the server-side infrastructure manages the communication between clients.

Client-Side Architecture: The client application is built using various programming languages such as Java, Kotlin, and Objective-C for Android, iOS, and other platforms. It also uses end-to-end encryption to ensure the privacy of user messages.

Server-Side Architecture: The server-side infrastructure is built using Erlang, which is known for its high concurrency, reliability, and fault-tolerance. It consists of a distributed system that manages the routing of messages and the storage of user data.
